Abstract

The discrete element method (DEM) was used to stimulate creep processes in granular materials. The authors present the main features of the numerical model, which include a new viscous mechanism for particle sliding, a new feedback technique for maintaining constant stress during creep, and a scaling technique that allowed monitoring the long‐term creep behaviour of a granular assembly. The creep behaviour of the numerical model exhibited the essential characteristics of soil creep—a creep rate that decreased rapidly with time, an increase in the creep rate with the applied deviator stress, and the beginning of creep rupture. The model's numerical performance is discussed, and representative results are presented.

Abstract

An algorithm is presented for creating a flexible boundary to analyse three‐dimensional assemblies of spheres. It can be used to study localization phenomena in particulate materials. The boundary is composed of adjoining triangular plate elements which are connected at their corners to the centres of neighbouring spheres. The applied external boundary stresses create traction forces on the plates, which are distributed among the plates’ particles. The boundary performed favourably in tests on a large assembly of particles when only contact and rotational damping were used. Plane strain compression tests on assemblies with flexible and periodic boundaries revealed a lower strength with the former. This result could be due to the greater restraint on particle movements produced by periodic boundaries or to the early development of a column buckling failure pattern of the assembly with flexible boundaries. No shear bands were observed in the assembly.

Abstract

The overall goal of science is to build a valid and reliable body of knowledge about the functioning of the world and how applying that knowledge can change it. As personnel and human resources management researchers, we aim to contribute to the respective bodies of knowledge to provide both employers and employees with a workable foundation to help with those problems they are confronted with. However, what research on research has consistently demonstrated is that the scientific endeavor possesses existential issues including a substantial lack of (a) solid theory, (b) replicability, (c) reproducibility, (d) proper and generalizable samples, (e) sufficient quality control (i.e., peer review), (f) robust and trustworthy statistical results, (g) availability of research, and (h) sufficient practical implications. In this chapter, we first sing a song of sorrow regarding the current state of the social sciences in general and personnel and human resources management specifically. Then, we investigate potential grievances that might have led to it (i.e., questionable research practices, misplaced incentives), only to end with a verse of hope by outlining an avenue for betterment (i.e., open science and policy changes at multiple levels).

Abstract

We present an overview of research on spillover effects within firms and introduce a classification of the literature. We divide spillovers into either technological or social in nature. In our classification, a technological spillover is one in which an agent rationally responds to a cue in the workplace that does not rely on the identity or characteristics of a coworker. Social spillovers, on the other hand, may be thought of as arising from the social preferences of an individual or social norms established in the organization.

Abstract

This chapter examines the efforts undertaken to restructure the legal education system in South Africa and Nigeria. It investigates the connection between contextual influences and professional development, particularly with respect to the concept of legal information literacy and the value of acquired educational skills in the context of legal practice. The chapter provides insights to the needs and challenges for graduate requirement for legal information literacy skills in the effort to ensure productivity in the legal education system in Africa. Data were obtained using both quantitative and qualitative approaches. Outcomes from the study were supportive of the importance of information literacy as central to the development of professional competence. Findings also point to a need for greater collaboration between the legal education system and the legal profession in narrowing the gap between the teaching and practice of law specifically in the design and implementation of an information literacy framework for the legal education system.

Abstract

This chapter examines the role of leader workaholism in relation to their own and their followers’ well-being. We begin with an overview of workaholism, along with a description of how workaholism may relate to typical leader behaviors. We propose a conceptual model linking the various components of workaholism to leaders’ well-being and followers’ well-being. In our model, we propose that leaders’ workaholism can negatively influence their own well-being, and also their followers’ well-being through interindividual crossover of affective, cognitive, and behavioral components of workaholism. Furthermore, the negative well-being outcomes experienced by the workaholic leader can also crossover to the followers through interindividual strain–strain crossover. Several moderating factors of these relationships are discussed, as well as avenues for future research.

To explain how cumulative efforts contribute to learning and literacy development.

Abstract

Purpose

To explain how cumulative efforts contribute to learning and literacy development.

Design/methodology/approach

A representation of how efforts lead to lasting growth is discussed through a variety of historical and current perspectives across content disciplines. This chapter includes depictions of how positive experiences can promote further success and recognizing one’s cumulative efforts and the effects from those are fundamental to educational attainment.

Findings

The value one places on tasks such as reading or writing is often aligned to the frequency with which those events occur. Students view their time and effort as capital; they are students’ most valued possessions, and how they allocate these commodities is a choice.

Practical implications

For students to become avid readers and writers, we must utilize a host of strategies to impress the notion that these activities are worth their attention, time, and investment.

Abstract

As the field of leadership education continues to prioritize learning in leadership, it is important to ask the question: What do we know about the learning process itself? Conceptual change, a learning framework used in educational psychology, can help to explain learning in leadership. Research on conceptual change in the social sciences is emergent and ripe for further exploration. Until the results of such research are readily available, there are some pedagogical tools produced by conceptual change researchers that leadership educators might find valuable in curriculum design. This paper introduces conceptual change theory and research to leadership educators as a viable framework from which to research learning in leadership, and presents pedagogical tools that encourage deeper learning through conceptual change
